RAIL-ANCHOR.

. Specification of Letters Patent.

Patented @ct. 11, 131%.

Application filed December 27, 1915. Serial No. 68,811.

its purpose is to provide a simple and im proved device which will operate efliciently in preventing longitudinal creepmg of rallway rails on the ties.

The object of the invention is to provide a red anchor constructed for bolting to the rail, and arranged to be secured against movement with respect to the tie, so that creeping of the rail is thereby prevented.

y improved rail anchor is adapted to be connected to two adjacent ties, so that longitudinal movement of each rail in either direction is prevented by the resistance of two ties, and turning or rolling movement of the anchor is also prevented. In this way any tendency of the anchor to tilt longitudinally of the rail is overcome, and the results are much more satisfactory than when an anchor is connected to one tie only. A further feature of the invention relates to the simplified construction whereby the anchor is secured against movement with respect to two adjacent ties, and is secured to the web of the rail at an intermediate will appear more clearly in the following point by means of a single bolt. Still another object is to provide a rail anchor of the kind described having means for engaging the lateral sides of the rail spikes, thereby securing the rail anchor against movement with respect to the ties, and also preventing turning of the spikes away from the rail. By meansof my invention I am also able to secure one rail against movement with respect to the two ties which are adjacent the splice on the oppositerail of the track.

These and other objects of the invention speclfication, taken in connection with the accompanying drawings, in which one em bodiment of the invention is illustrated.

In the drawings- Figure 1. shows a perspective view of my improved rail anchor in position with respect to a railway rail supported upon the usual ties;

. and the shorter axis of Fig. 2 is a transverse vertical section through the rail anchor and the rail to which the same is applied;

Fig. 3 is a sectional view, taken on the line 3-3 of Fig. 2; and

Fig. 4: is a plan view of a portion of a railway track, showing the preferred method of using my rail anchor.

Referring to Fig. 1 of the drawings, the two adjacent ties l0 and 11 are as shown as supporting a railway rail 12, having a head 12*, web 12", and base 12. My improved rail anchor comprises a plate 13, which is adapted to seat upon the base of the rail and to extend outwardly beyond the edge 12 of said base. The plate 13 is also of sufficient length longitudinally of the rail to overlap the two adjacent ties 10 and .11, and spiking apertures 14 and 15 are provided in the plate in such position as to overlie the ties 10 and 11, respectively, and to receive the usual rail spikes 16. These spikes are driven into the ties to engage the edge 12 of the rail base, and the heads of the spikes overlie and contact with the upper surface of the plate 13 adjacent the edges of the spiking apertures. It will therefore be apparent that when the spikes are driven to position, as described, movement of the plate with respect to the ties will be prevented. I

upturned lip 17 is formed integral with the plate 13 along the inner edge thereof, and midway between the ties lO'and 11, this lip being adapted to lie parallel to and in close contact with the web 12 of the rail beneath the head 12. This lip is provided with an aperture 18, which is preferably of elliptical or other non-circular form, as shown in Fig. 3, and the web 12 is provided with an aperture 19 adapted to aline with the aperture 18 in the lip 17. The alining apertures 18 and 19 are engaged by the bolt 20, which is provided with a portion 20, adjacent the head thereof, having an elliptical or other suitable cross section adapted to fit the aperture 18 in the lip, whereby the bolt is held in non-rotative engagement with the lip. The diameter of the aperture 19 the aperture 18 are preferably made somewhat larger than the diameter of the bolt, in order to allow suitable working clearance for an elfective adon the rail. A

justment of the rail anchor split washer 21 is placed on the bolt opposite the lip 17, and a nut 22 engages the extremity of the bolt to secure the parts in ad usted relation. The rail 12 is secured to the ties opposite the plate 13 by means of the spikes 23.

The rail anchor is preferably formed from wrought steel, and may be formed from a sheet of metal by cutting the plate 13 having the extension 17, which is later bent upwardly to assume the position shown in the drawings. This plate has the edges 13 thereof, adjacent the web of the rail, inclmed outwardly from the web at each side of the lip 17, thus permitting a more convenient and accurate adjustment of the rail anchor to the rail, while at the same time providing for the formation of the plates in an economical manner from a sheet of metal, since the portions of the plate cut away from each side of the lip 17 may form the ends of the plate 13 of other rail anchors.

I prefer to attach my improved rail anchor to the rail on the inner or gage side of the rail, as shown in Fig. 4.

From the previous description it will be understood that the rail anchor may be placed in this position without interfering with the rolling stock, and this location also permits any desired number of spikes 23 being used on the opposite side of the rail to engage closely the edge of the rail base and prevent lateral movement of the rail on the ties. I also prefer to locate the rail anchor opposite the splice or joint 24, by means of which the meeting ends of the rails 25 opposite the rail 12 are connected. This splice is usually formed by means of angle bars bolted to the rails and spiked to the ties, as is well known in the art, so that the joint formsa connection between the rails 25 and the ties 26, adjacent the joint, whereby the creeping of such rails with respect to those ties issubstantially prevented.

Will

It will be understood that according to the usual railway practice the joints of opposite rails of the track are staggered with respect to each other so that according to such usual practice the rails 25 would be fixed by the joint 24 relatively to the ties 26, while the opposite rail 12 would be permitted to creep with respect to the opposite ends of such ties. It therefore follows that when there is no anchor at the opposite ends of these ties 26, the ends of the ties at the splice will tend to travel with the rails 25, while the unanchored ends of the ties will stand still. The ties therefore tend to become displaced from a position at right angles to the rails, which action may narrow the gage of the rails at the splice, since the angular movement of the ties tends to draw the opposite rails toward each other. By means of my invention this tendency and the evil results following therefrom are overcome, since my improved anchor may be located opposite the joint 24 so as to anchor the rail 12 to both of the ties 26. In this way the opposite rails of the track are secured against creeping with respect to the two ties on opposite sides of each joint. It will be understood, however, that the rail anchors may be otherwise located if desired, and it will be also understood that the application of the anchor to one length of rail between the ends thereof will relieve the splices at the ends of the rail of any tendency to horizontal movement, owing to the creeping of the rails, which results in a more satisfactory support of the rails at the splice than is obtained when the rail forces the members of the splice from the tamped up bed beneath the same. 4

My improved rail anchor closely fits the rail base and the web of the rail, and is united to the web by means ofa single bolt, so that it may be very easily and economically attached to the rail, and will at the same time effectively overcome the tendency of the rail to creep in either direction. This is a distinct advantage over the usual rail anchors, which are attached to the rail base and which have a depending arm adapted to contact with one side of a tie to prevent creeping of the rail in one direction only, and when the rail moves in the opposite di, rection, owing to the expansion of the rail or to the movement of the rolling stock in the opposite direction, the depending arm moves away from thetie and the parts of the anchor lose their grip on the rail, so that the device is no longer effective without readjustment. It anchor maintains its adjusted relation to the rail after being assembled thereon, and it is only necessary to tightenthe nut carried by the bolt in order to take up the wear which occurs on the coacting surfaces of the anchor and rail. The preferable form of construction in which the lip 17 contacts closely with the web of the rail is of particular advantage, since a relatively large wearing surface is thereby obtained, a relatively short bolt may be used, and shearing stresses on the bolt are greatly reduced, as compared with a structure in which, for instance, the lip wedges between the head and base of the rail. It will be seen that the walls of the spiking apertures serve to prevent the spikes from turning outwardly away from the rail base. Since this anChOr overlaps and is secured to ,two adjacent ties, all tendency of the anchor to tilt longitudinally of the rail is overcome as well as the tendency of the ties to turn or become displaced from a position at right angles to the longitudinal axes of the rails.
